CPU performance – The MELSEC iQ-F Series has a CPU capable of high-speed processing with an instruction operation speed (LD instruction) of 34 ns. In addition, the CPU supports the execution of structured programs and multiple programs, SFC language, ST language, FBD/LD language, etc.

Controllable I/O – Up to 512 points can be controlled when using remote I/O (CC-Link and AnyWireASLINK).

Sufficient built-in communication ports – Ethernet and RS485 communication ports are provided as a standard. Seamless connection with various peripheral devices and upper-level devices can be realized without additional units.

SD memory card slot – Programs can be updated and read from an SD card. The SD memory card can also be used to log data, which is useful for analyzing equipment status and production conditions.

Substantial built-in functions – A max. 200 kpps built-in positioning function and high-speed counter function are also equipped. Various convenient functions, including remote monitoring with the Web server function, are provided.

Motion control supported – High-accuracy positioning control is possible with the CC-Link IE TSN-compatible motion module and SSCNET III/H-compatible simple motion module. Complicated positioning control, such as synchronous control, is possible even with a micro PLC using reduced wiring.

Built-in analog I/O (with alarm output) – Analog I/O ports are provided as standard on the screw terminal block type CPU module. Inputs from sensors and outputs to drive devices can be controlled without module expansion.

Powerful security functions – Various security functions, including IP address filter and authorization keys, are provided. Valuable data and devices are protected.

Battery-less and maintenance-free – The program memory uses non-volatile memory, data can be held without a battery. An optional battery can be added to expand the data holding range.
